Sorry that it's not techically betta related, but with my new (well new to me) tank I got that is 1.5g, how should the cleaning schedule be? It has a rosey red minnow and a few ghost shrimp inside. No filter, just the tank with stones and an air pump/bubbler thing. Thanks :)

1.5 gallons needs full cleaning every other day at least.....and pretty much any other fish besides a betta isn't going to be able to take that. I, personally, don't know of any kind of fish besides the Betta Splendens that can live in an uncycled tank with regular 100% changes, and I do know shrimp are delicate and need an established tank....

On top of that, I'm pretty sure minnows are schooling fish and need friends....and 1.5 gallons is just the bare minimum for a single betta....I don't know of any other fish that can live in a tank that small. Your probably going to want to re-home that minnow, or get it a larger tank and some friends, and probably move those shrimp too a cycled tank, or re-home them.....

I moved the minnow and shrimp into the divided 10g so they have about 3-4 gallons. I have Starburst, one of my males in the 1.5g now with a heater so the temp. is a steady 76-77 degrees. Would I still need to do every 2 days? Or maybe 3?
